    (a) Natalizumab binding on VLA-4 expressing cells (PFSK1) compared with non-expressing cells <t>(HEK293/T17)</t> by flow cytometry using an FITC-conjugated secondary anti-IgG 4 . (b) Effect of natalizumab blocking antibody HCA250 on natalizumab and milk (T2) IgG 4 binding to PFSK1 cells. Serum was used at 1:40 dilution. Each column corresponds to average binding of IgG 4 on PFSK1 (geometric mean of the florescence intensity – GMFI – of cells incubated with the sample) from three replicates. Error bars are standard error. (c) Stability of expression of VLA-4 by PFSK1 cells. PFSK1 cells from passages 7 to 13 were incubated with either natalizumab at 10 µg/ml or with secondary only control. p -value for comparing binding of natalizumab to secondary only was calculated using unpaired t -test. Variances were compared using F -test. (d) Natalizumab detection in serum from treated patients positive for anti-natalizumab antibodies were compared with anti-natalizumab negative samples ( p < 0.0001, Mann–Whitney test) using an anti-IgG 4 antibody. Each dot corresponds to the binding of IgG 4 on PFSK1 (ratio of GMFI of cells incubated with the sample to cells incubated only with secondary antibody) from each serum sample, tested in three independent experiments.

    (a) Natalizumab binding on VLA-4 expressing cells (PFSK1) compared with non-expressing cells (HEK293/T17) by flow cytometry using an FITC-conjugated secondary anti-IgG 4 . (b) Effect of natalizumab blocking antibody HCA250 on natalizumab and milk (T2) IgG 4 binding to PFSK1 cells. Serum was used at 1:40 dilution. Each column corresponds to average binding of IgG 4 on PFSK1 (geometric mean of the florescence intensity – GMFI – of cells incubated with the sample) from three replicates. Error bars are standard error. (c) Stability of expression of VLA-4 by PFSK1 cells. PFSK1 cells from passages 7 to 13 were incubated with either natalizumab at 10 µg/ml or with secondary only control. p -value for comparing binding of natalizumab to secondary only was calculated using unpaired t -test. Variances were compared using F -test. (d) Natalizumab detection in serum from treated patients positive for anti-natalizumab antibodies were compared with anti-natalizumab negative samples ( p < 0.0001, Mann–Whitney test) using an anti-IgG 4 antibody. Each dot corresponds to the binding of IgG 4 on PFSK1 (ratio of GMFI of cells incubated with the sample to cells incubated only with secondary antibody) from each serum sample, tested in three independent experiments.
